By observing the Earth from space, satellites provide essential information on ocean, ice, land environments, and the atmosphere. Earth-observation satellites help us monitor and protect our environment, manage our resources, and ensure the safety and security of Canadians. Satellite imagery and expertise is also used to support global humanitarian efforts and sustainable development.

Canada is renowned for the exceptional instruments on its science satellites. Some of these expand our understanding of the origin, formation, structure, and evolution of celestial bodies and the universe. Others study the physics and effects of phenomena such as aurora borealis on Earth's magnetic field.
